49.

Mechanical impedance is the ratio of

A.	rms force to rms velocity
B.	rms force to rms displacement
C.	rms velocity to rms displacement
D.	none of the above

Answer: Option A

Explanation:

In force voltage analogy force is analogous to voltage and velocity to current. Just as 40-2 force/velocity = mechanical impedance.

For the system in the given figure the characteristic equation is

16-87

Answer: Option A

Explanation:

Transfer function = 41-87

Hence characteristic equation is 41-87-1
